Abstract
Starting from tetronate 1 (R = CH2OH), a short photochemical access to the 3,12-dioxatricyclo[8.2.1.06,13]tridecane-skeleton 2 of briarellin and asbestinin diterpenes has been explored. In the course of these studies, a number of surprising observations were made. For example, a two-step reaction pathway to the bicyclic ketolactone 3 was discovered, which is based on tetronate 1 (R = COOMe).
